Is there any way to add a line count column that would always have the right number when sorted?

Is that something that might be considered for an update? I think in some instances people would like to see a line count at the beginning, like if you enables lines in textpad. showing :

1
2
3
4

and if you sorted one of your columns the updated view would still show :

1
2
3
4

with the refreshed data

It would be nice to have as an option.

What if I am not using xsl? I am using the default grid table with the datagrid class.

If I were to change over to xsl, how do I get it to look like the default grid table?
